BAKER S OV EN.

SPECIFICATION forming part of Letters Patent No. 534379, dated February19, 1 895.

Application filed August 25,1894. Serial No. 521,284. (No model.)

To all whom it may coi worn:

Be it known that I, ERNST SCHILG, a subject of the Emperor of Germany,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Bakers Ovens,ofwhich` the following is a specification.

The object of my invention is to obtain such results as may be naturallyattributable to the Construction hereinafter set forth, the especialfeatures of novelty being enunerated in the claim at the end of thespecification.

In the accompanying drawings: Figure I represents a horizontal sectionof an oven embodying myinvention, the plane of section being indicatedby the line 1-1, Fig. VII. Fig. II represents a like section thereof inthe plane indicated by the line 2-2, Fig. VII, looking downward. Fig.III repres'ents a like section thereof in a like plane to the precedingfigure, looking upward. Fig. IV represents a like section thereof in theplane indicated by the line 4-4, Fig. VII.- Fig..V represents a likesection thereof in the plane indicated by the line 5-5, Fig. VII. Fig.VI represents a plan View thereof. Fig. VII represents a cross-sectionthereof in the plane indicated by the line 7-7 Fig. I. Fig. VIIIrepresents a front view thereof. Fi g. IX represents a Vertical sectionof a portion of the front wall thereof in the plane indicated by theline 9--9, Fig. IV. p

Similar letters of reference indicate similar parts in all the figures.The letter A indicates the hearth orbakingchamber, B the fire-chamber,and C, D, air-` chambers above and below the baking-chamber. Theair-chamber C is below the baking chamber A between it and thefire-chamber B and the air-chamber D is above the bakingchamber; and thelast named air-chamber has outlets D' each provided with a damper D Theair-chamber D communicates with the fire-chamber B by means of flues e,in this example two in number which are formed in the rear wall of theoven, opposite to the front wall thereof, in which latter are twoopenings with doors F, Gr, one' affording access to the baking-chamberand the other to the fire- -chamber.

The longitudinal passages on either side of the fire-chamber B leaddirectly back to the flues e, and said passages at their forward endeare open laterally toward the fire-place while at their rear ends theycommunicate with the rear of the fire-chamber. The draft through theflues draws the fire from the fireplace laterally into said longitudinalpassages as well as backward, and consequently when the door of thefire-chamber is opened there will be no forward Shooting of flame as isthe case when there are flues at the front of the oven.

By the location of the flues e only in the rear wall, incontradistinction to the front wall of the oven, the attendant baker isrelieved from the heat which would otherwise radiate from the front ofthe oven.

The door F, to the baking-chamber is hinged, as at F' (Fig. IX) and isweighted in such a manner as to counter-balance, that is to say, thedoor will automatically retain any position to which it may be adjusted;the weight used for this purpose being an integral part of the door.

The top or partition wall dividing the baking-chamber A from theair-chamber D is arched as shown in Fig. VII and at the center thereofis a lon gitudinal beam H of metal, which is anchored in the front andrear walls of the oven, the purpose of this beam being to preventwarping of said partition wall under the influence of the heat to whichit is subjected.

Both air-chambers C and D are divided into compartments, as shown inFig. VII; but may be continuous.

The purpose of the air-chamber C is to attemper the heat of thefire-chamber B, in its action on the baking-chamber; and it is evidentthat said chambermay be omitted.

hat I claim as my invention, and desire to secure by Letters Patent,is-- In a baker s oven having a fire-chamber' with a fire-place at thefront end thereof and a baking-chamber above said fire-chamber,

vertical flues e in the rear wall of the oven,

extending to the top of the oven above said baking chamber, longitudinalpassages `on either side of said fire-ehamber communicatng only withsaid reat' flues and. with said fire-chambe' at its front and real'ends, the front openings from the fire-chambe' to said passages beinglocated directly at the side of the fire-place, whereby heat and flameare drawi laterally and real-ward from said fireplace to said rearfiues, substantially as set Io fol-th.
